Abstract: The port is the node that provides cargo reloading and displacement services, undertaking a large number of cargo circulation operations. It is an important direction in the future to study the co-competition relationship between ports in order to realize the healthy development of port enterprises. There are many factors affecting the relationship between ports. By introducing the role of government, the game model between government and port enterprises was established by using evolutionary game theory, and the interaction between government and port was analyzed. MATLAB software was used for simulation experiment. The research shows that the direction of evolution is mainly related to the government revenue and the rectification cost of port enterprises. By controlling these two parameters, the co-competition relationship of port market can be adjusted.

摘要： 港口是提供货物换装位移服务的节点，承担着大量的货物流转作业，研究港口间竞合关系以实现港口企业健康发展是今后的重要研究方向。影响港口间关系的因素较多，通过引入政府的作用，采用演化博弈理论建立政府与港口企业博弈模型，分析政府与港口之间的相互作用关系，并且运用MATLAB软件进行仿真实验。研究表明：演化的方向主要与政府收益和港口企业的调整费用大小相关，通过控制这两个参数的大小，可以调节港口市场的竞合关系。
